A fine viewpoint, but the cairn has gone (was getting a bit big).

Great walk that's pretty accessible for most people to achieve, challenging but doable! The route I took incorporated Lord Hereford's Knob. I published it on Komoot here: https://www.komoot.com/tour/1576268965 And on my blog here (with extra commentary for my own entertainment!): https://weekendwalk.co.uk/route/hay-bluff-walk/

Hay Bluff is a prominent hill at the northern tip of the Black Mountains, an extensive upland massif which straddles the border between south-east Wales and England. The mountain sits at the point where the main northeast-facing escarpment of the Black Mountains meets the northwest facing escarpment, the next peak to the west being Twmpa. The flat summit of Hay Bluff which is marked by a beautiful welsh dragon trig pillar at a height of 677 metres (2,221 ft) overlooks the middle Wye Valley and the book town of Hay-on-Wye.

Hay Bluff stands at 2,221 feet (677 m) at the northern end of a wonderfully runnable ridge. The Offa's Dyke path and the Llanthony horseshoe route both pass it. It's also a good, shorter loop from the Hay Bluff car park to the north, to include the excellent Cat's Back ridge if you have time. Great views to the north over Hay.

The Black Mountains offer challenging upland routes. Peaks like Twmpa (Lord Hereford’s Knob) are rated as challenging, forming part of the great northwest scarp. The Twyn Llech (Black Mountain) Summit, while having shallow gradients along its ridge, can be very exposed to wind, making it feel like a true mountain challenge. For specific challenging routes, you can explore the 'Running Trails around Hay' guide, which includes routes like 'Hay Bluff – Pen y Fan loop from Hay on Wye' and 'Llanthony loop from Hay-on-Wye', both rated as difficult.
While many outdoor areas in the UK are dog-friendly, it's essential to be mindful of livestock and ground-nesting birds, especially during lambing season or in areas with conservation efforts. Always keep dogs under close control, preferably on a lead, and follow the Countryside Code. Specific information on dog-friendly trails for the peaks around Hay should be checked locally or on individual route descriptions.
The best time to hike the peaks around Hay generally depends on weather conditions. Spring brings wildflowers like pink boronia and flowering banksias, attracting diverse birdlife. However, the ground on peaks like Twyn Llech (Black Mountain) Summit can be peaty and very wet even in good weather. Winter can be challenging with tough winds and potentially muddy conditions, as noted for Merbach Hill, so good boots are essential. Late spring to early autumn typically offers the most favorable conditions.

The Offa's Dyke Path also passes along this ridge. The ground here is often peaty and can be very wet, even in good weather, adding to its distinct character. Despite its relatively shallow gradients, the exposed nature of the summit means the wind can be quite strong, giving it a true mountain feel.
